With the summer months fast approaching, you’ll need an air conditioning unit to keep you cool and dry. We know it’s overwhelming to search for a new unit with all the ones available on the market.

Some are best suited for bedrooms while others for kitchens. Others are quiet while some are loud and powerful. Others still are more appropriate for smaller spaces while some for larger ones.

Not to worry, we’ve taken the burden of searching off your shoulders and rated some of the best window air conditioners to make things easier on you.

How We Chose Our Ratings For A Window Air Conditioner

We considered several important criteria to evaluate each product that we rated.

The first is the unit’s cooling capacity. Those with a higher rating were able to move air through a room more efficiently, operate in different modes, and ultimately provide a hassle-free cooling experience.

Next, we considered the unit’s energy efficiency rating. Each air conditioner has an energy efficiency ratio (EER). The higher the EER, the greater the efficiency of the unit. Air conditioning units with a higher energy efficiency rating will allow you to save on your annual energy cost. Your actual annual cost will depend on how often you use the air conditioner and the cost of electricity in your region.

Ease of use is also an important criterion. A high-rated air conditioner will have features that are user-friendly. For instance, units with a remote control or auto restart capability are rated highly.

We evaluated the operational modes of each unit also. A unit with personalized modes was ranked higher than those with fewer options. Be sure to take a look at units with cooling modes, fan-only modes, and adjustable fan speeds.

Finally, we determined the cost of a budget window air conditioner. Anywhere between $100 and $300 is a reasonable price for a unit. While these types of units won’t have as many features or be multi-directional, they do come with at least a one-year warranty to cover the cost of a compressor breakdown.

Here are 10 of the top-rated window air conditioners on the market today:

LG Energy Star Window Air Conditioner
  • 3 Cooling & Fan Speeds with Auto Cool
  • 4-Way Air Direction
  • Power Failure Auto Restart

5/5 stars

A leader in the market for large home appliances, LG brings consumers this all-star window air conditioner.


It is a powerful, energy-efficient unit that has the capacity to cool a room of up to 340 square feet. It has a maximum airflow of 220 cubic feet per minute (CFM). When the temperature in your rooms drops to a certain degree, it shuts off in three-minute intervals to keep you from cooling an already regulated area.


The LG unit has an EER of 12.1, which is well above the minimum amount required to be Energy Star stamped.


It is more expensive than other units and heavy, weighing 54 pounds.


Inspect the internal fan of this unit weekly to ensure that it is not overworked.


While the unit does not automatically shut off, it has a timer so that you can control how long it runs. It has an auto-restart feature in which the unit will resume operations during a power outage.


You’ll be thankful for this machine during high humidex readings as this unit pulls 2.2 pints of moisture per hour out of the air. It features a dehumidifying mode to remove moisture in the air more effectively without changing the temperature of the air.

5/5 stars

This is one of the most compact and lightest units on the market, weighing at 40 pounds. The Keystone KSTAW05B has a cooling power of 5,000 British Thermal Units (BTU), which makes it an excellent unit for small rooms of up to 150 square feet. It doesn’t produce enough power to cool a typical master bedroom or other larger rooms.


Because of its small size and low power, though, it will cost less to run this unit than other air conditioners. It has an EER rating of 11.2, making it an energy-efficient option.


It contains many convenience features including a remote control, programmable timer and auto mode. Other less common features include a dehumidifier and sleep mode.


The unit comes with a five-year warranty on the compressor part, which is more than the typical one-year warranty that some similar models carry.


It also has a lower airflow than other units at 129 CFM. Despite the lower airflow, it is affordable, lightweight and compact — excellent for small rooms.

Buyer’s Guide:
 Choose A Window Air Conditioner That’s Right For You

When choosing a window air conditioner, you’ll need to keep in mind a few things.

Be sure to consider the size of your space and the cooling performance of the unit. It’s easy for anyone to say that an air conditioner suitable for cooling spaces of up to 150 square feet will not be suitable to cool a larger living room.

Think about energy ratings as well since the higher the rating, the more you’ll save annually on your energy bills.

Finally, consider installation and operation modes. Be patient and understand that setting up a window air conditioner will take longer than a couple of minutes. As well, depending on your preferences, choose a unit with the operational modes you are looking for.
